nated by the same reference characters in the several views..

Referring to Figs. l, 2, 3 and 4, main side frames l and 2 are parallelly carried by the base plate 3. Journaled in the forward ends of these frames is a transverse main shaft 4, on the extreme end of which shaft is located a sprocket 39. A transverse shaft 5 (Fig. 1) has on one of its ends a sprocket 6. A sprocket chain 7 connects sprockets 6 and 39,. a tension idler 8 carried on an eccentricadjustable stud 9 arranged on side frame 1 serving to keep the sprocket chain taut.

Fastened to opposite portions of shaft 5 (each alongside but outside its adjacent frames 1 or 2), are a 'pair of eccentrlcs l() and 10 (Fig. 1), and on each of these eccentrics is an eccentric strap 11. These straps each carry a connecting rod 12 which ends in an -eye 13 (Fig. 2) and is bolted to a pusher 15 (Fig. 2) by means of a bolt 14.

Anchored to the top side of pusher 15 is a thin plate 16, approximately the thickness of a Hat carton, and the inner edge of this plate rests upon a bottom plate 17 of a hopper 20 (see, for a moment, Fig. 8, wherein it will be noted that pusher 15 has a leaf 15, extending back between frames 1 and 2, supported by parallel guideways 22).

Hopper 20 is of the necessary dimensions to contain a stack of folded or fiat cartons 100 (Figs. 2 Vand 8), and for purposes of loading the cartons into said hopper it is open on top 4and part of its front side is cut out, leaving the wings 21 (Fig. 2). The lower corners of wings 21- 21 are cut away to leave clearance for the passage of pusher plate 16. Nor does a back plate 18 of the hopper quite reach to the bottom plate 17; this plate 18 is so arranged as to establish a gate the height of what is equal to the width of one iiat carton as shown at 23, Figs. 6 and 7.

Immediately behind the back plate 18 is located a feed roll 24 mounted onfa transverse shaft 25. This shaft is carried in sliding journals 26, one in each main frame (Figs. 6 and 7), and these journals are pressed downwardly by springs 27 in caps 28. A set screw 29 in each cap serves to regulate the pressure of these springs.

Feed roll 24 presses upon another feed roll 19 (Fig. 4) mounted on shaft 5 (Figs. 6 and 7). f

Shaft 5 has fixed on it also a gear 30,

(see Fig. 2). The pitch lines ofv these gears A32 and 33 are supplementary tracks 34 and 35, which for a portion of their length parallel the lower tracks, but which at their inner ends are suitably curved (see Figs. 6 and 7), and then extend in between the eut away portions of rollers 24 and make connection with the back plate 18 of hopper 20, the lower faces of the horizontal inner lengths of these' tracks 34 and 35 being at a distance approximately the thickness of a folded carton above the upper faces of tracks 32 and 33, (see said Figs. 6 and 7). Each of the upper tracks 34 and 35 is suitably recessed to receive predeterminedly a pawl 36, the tooth of each of which normally extends{ below its associated track and is maintained in this position by means of a leaf spring 38, as shown in Figs. 6, 7 and 8.

Fastened to main shaft 4 (Fig. 1) is a l cam 40 (Figs. 2 and 5) and engaging with this cam is a bell-crank lever 41 (Figs. 1, 2, 5, 6, 7 and 8), the upper end of which is bifurcated (Fig. 2) with each leg of the bifurcation carrying a pawl 42 (Figs. 2, 6 and 7). Each pawl 42 is connected tothe bell-crank lever 41 by means of a pin 43 (Figs. 6 and 7) and. each is maintained by a spring 44 (said Figs. 6 and 7) in a position with its nose a little above the upper surface of tracks 32 and 33.

A shaft 45 (Fig. 1) is mounted in suitable bearings in side frames 1 and 2, and said shaft has mounted thereon one or more stopgages 46, each of which normally extends i slightly above the upper surface of tracks 32 and 33 (Figs. 5, 6, 7 and 8). Shaft 45 carries gear 47 (Fig. 4) at one of its outer ends, said gear 47 meshin with a gear 84 (Figs. 1 and 4) on a shaft 4 (Fig. 1).

Fixedly mounted on main shaft 4 (Figs. 1, 5 and 8) is a cam-48, and this cam (Fig. 8) controls the upper edge of a lever 49 which is pivotally mounted on a stud 50 'anchored in a boss on the inner side of side frame 1.

' a stud v53set inside frame 1 (Fig. 8).

Segment 52 meshes with a gear 54 which is yfixedly mounted upon a shaft 55 hung in frames 1 and 2 (Figs. vund 8). Also fastened upon shaft 55 is a gear 56 (Figs. 5, 6 and 7) which meshes with a segment 57 that-is in turn fastened to a shaft 58 (Figs. 5, 6, 7, and 8). Shaft 58 is journaled iu a suitable bracket 59 carried between main frames 1 and 2v and extending transversely of the axis of said shaft 58, and fixedly but spacedly mounted thereon are two parallelly mounted turning arms 60 contiguous to tracks 32 and 33. Y

The main shaft 4 carries at a point be yond the main frame 2, a track-cum 61 (Fig. 2), and, engaging with this cam by means of a roller stud 63 (Figs. 2 and 4), is a rockshaft 62 (Figs. 2 and 3). This rock-shaft is held in place by means of suitable bearings 64 vand 65 (Figs. 2 and 4). Carried fixedly by rock-shaft 62 is an upstanding lever 66 (Figs. 2 and 3) and the upper end of said lever is cut into a gear segment which engages with an idler gear 67 held in place near the outer end of a sleeve 68 (Figs. 2, 3 and 4) that extends outwardly from main frame 2. A plunger 69 (Figs. 2, 6 and 7) has a portion thereof cut into a rack to engage with idler gear 67, and the same is free to slide in sleeve 68 and also rotate upon its axis to a limited extent. Said plunger has its inner end formed into a double bevel, as' shown in Figs. 6, 7, 9, 12 and 13; and also carries a pin 70', to be guided by a slot 7l cut in sleeve 68, as shown best in Fi 4.

A shaft 72 (Figs. 1, 3 and 4) is mounted in 'frames 1 and 2 and lixedly carries a pair of similar sprockets 73; and a shaft 7 i mounted parallel to shaft 72 similarly car ries a similar pair of sprockets 75. Two endless chains 76 are laid around these sprockets (see particularly Figs.1, 6 and 7)` and are kept. in a taut condition by means of idlers 77 carried on .arms 78 (Fig. l) extending from shaft 79 which is held iu place between frames 1 and 2k (Figs. 1 and 4). Each of these chains 76 carries equidistantly spaced thereon a plurality of lugs 80, each lug extending outwardly of the path of travel of its chain, and eachiug on one of the chains being alined trausversely of the machine, with a lug on the otler chain as shown in Figs. 1, 3, 4, 6, 7 an 8.

A' shaft 81, parallel to shaft 72 and di similar sprockets 82. On shaft 55 are a pair of mutually similar loose running sprockets 83. Laid around each set of sprockets 82 and 83 is a chain 87. Each of these chains 87 carries equidistantly spaced thereon a plurality of lugs 80, these lugs too, extending outwardly of the path of travel of its chain and each lug on one of the chains being alined with a lug on the other chain as shown magere in Figs. 1, 3, 6, 7 and 8. It will be seen, also, that each lug on a horizontal length of a chain 7 6 is vertically alined, but spaced from a lug on a horizontal length of a chain 87 (Figs. 6 and 7).

To keep each chain 87 in tens1on an ldler 90 is hung from a bracket 91 in line with each chain (see Fig. 1), said brackets being held in place by a shaft 98 mounted in side frames 1 and 2.

Shaft 4 carries adjacent its extreme outer end bearings 85 (Fig. 4) a driving pulley 86.

To insure the proper travel 1n umson of chains 76 and 87, shaft 72 fixedly carries a gear 88 which meshes with a gear 89 ixedly carried by shaft 81 (see Fig. 1).

An eccentric 92 (Fig. 1) is fastened to shaft 4, and by means of an eccentric strap 93 (Fi 1, 2 and 4) and a connecting rod 94, sai eccentric causes a lever 95, p1voted on shaft 81, to oscillate once for each revolution of the shaft 4. The lever 95 carries a pawl 96 which engages with a ratchet wheel 97 (Fig. 1), fastened to-shaft 81, and thereby causes the chains 76 and 87 to advance the space of one transverse line of alined lugs 80--80-80-80 for each full revolution of main shaft 4.

Making temporary assumptlon that a lowermost blank 100 (see thestock of blanks shown in Fig. l) has been as hereinafter described partially thrust from its normal lie in hopper 20, and referring to Fig. 9, 1t will be noted that while the yet iat blank is being fed forward by its engagement between the feed rolls 19 and 24, the forward edge of the blank cornes underneath the plunger 69 at a time when sald plunger 1s extending into the machine transverselyof 'the latter only sufficiently to engage portlon of the left end (relatively of Fig. 2) folding flaps of the blank (see X, Flg. 3). With a little farther travel ofthe blank, as 1n Fig, 10, the plunger 69 is predeterminedly forced partially to rotate on its axls, by reason of said plunger being predeterminedly forced farther into the machine, the camslot 71 coincidently acting on pin 70 to partly turn the plunger on its axis and thus depress its nose 69A (Fig. 13) thereby to deflect the flaps 103A and 103B" (Fig. 14) as shown in Fig. 10. The nose 69A of the plunger is now below the plane of the undersurface of flap 103C. Further travel of the blank results in a predeterminedly adjustment of the plunger as shown in Fig. 11', the plunger now being located between upper flap 103C and lower Hap 103B, and the plunger nose now having been returned to its normal position by reason of the timed effect of the slot 71 upon pin 70 (Fig. 4). Figs. 12 and 13 show clearly the method of obtaining the preferably present doublebeveled end on plunger 69, the edge 69A being longitudinal with, but offsetl from, the

axis of the plunger and the edgev 69B being transverse to the axis but located in a horizontal plane tangent to the lowermost longitudinal edge of the plunger.

A complete rsum of the operation of the above-described embodiment of the present invention,vwhich should largely be obvious, 1s substantially as follows: A quantity of flat carton blanks 100 having been put into hopper 20, with the lowermost one resting on the bottom plate of the hopper (Figs. 2, 3, 4, 6, 7 and 8), the rotation of main shaft '5 causes its eccentrics l0 and connecting rods 12 (Fig. 1) to actuate the pusher plate 16, (Fig. 8) to force the lowermost blank out of the hopper while the superimposed blanks are restrained by reason of the contracted opening 23 (Figs. 6 and 7) in the back plate 18. The thrust movement of plate 16 is sufficient to cause the flattened blank to be engaged by the continuouslyrunning feed rollers 19 and 24, (Figs. 6 and 7), which are preferably covered with rubber or other friction material. As the blank is just ready to pass beyond these feed rollers, the hindmost edge of the blank snaps beyond the breasts of the terminal teeth of the springbiased` pawls 42, the forward edge of this blank having ridden upthe ramps of these teeth and subsequently the undersurface of said blank having maintained abnormally depressed said teeth. vAs said hindmost edge of the blank vnow clears said pawls, the latter function to advance the blank a 'further predetermined distance, due to thev timed coperation between cam 40 and bellcrank lever 41, to the end that the blank now comes to rest with its forward end resting against stop gage 46 (Figs. 6 and7).

As the blank is being fed forward by they feed rolls 19 and 24, the folding lapsat one end (the left-hand end relatively of Fig. 2 and the right-hand end relatively of Fig. 3) pass underneath the projecting bevel-edged plunger 69. This plunger has in the meantime, by the normal adjustment of the parts vhereinabove described, to wit, the cam 61,

the lever 66, the idler gear 67, etc., been advanced .so that its beveled edge is in the path of travel of the folding-flaps last-above mentioned, and is now about in the position shown at X in Fig. 3. Thereupon, and by means of said cam 61, said plunger is caused to move slightly in toward the center of the machine, and'simultaneously the projecting pin on plunger 69 engages with the curved portion of track 71 in sleeve 68 (Fig. 4), thus deflecting the beveled edge or nose of the plunger 69 downwardly. The ensuing twisting motion of the beveled nose of the plunger causes the adjacent folding aps of the blank to be forced out of the plane of the main body of the blank (as hereinbefore described in connection with Figs. 9 to 11 inclusive), and the further travel of the blank formed permits the beveled nose of the plunger 69 to enter between the two opposite flaps 103n and 103C as shown in Fig. 11. `When the blank has traveled thus far enough to permit the plunger to lie between these two flaps the plunger is caused to move rapidly in to-v treme position insidethe blank as just. de

scribed, the two turning arms 60, by means of the redetermined rocking of lever 49 (-Fig. 1i) due to the design of the cam 48 (Figs. 2 and 8) are caused to rotate about -their shaft 58, to expand the blank first lying to the'condition shown in Fig. 7 and then to .tlle'condition'shown in Figs. 8 and l; the

lcreasing edge 100A (Fig. 6) of the blank traversing an arcuate path which coincides with the curved portions of tracks 34 and 35 (Figs. 6, 7 and'8). It will be at this point seen that the elements comprising stop gages 46, plunger 69, turning' arms 60, and the curved ortions of tracks 34 and 35 coact toward insuring a successful, rapid and unerring expansion of the blank. S

While the blank is thus being formed, as described, when edge 100A (Fig. 6) approaches its uppermost or final position, it causes the pawls 36 (Fig. 6) to recede into their aforesaid abnormally-accommodating recesses in tracks 34 and 35, and immediately after said edge -100A has snapped beyond these pawls, the latter drop behind said edge and hold the blank inits substantially F or open position, as best shown in llext, the chains 76 and chains 87 are caused to move forward the distance of one of the longitudinal divisions marked olf by two adjacent lugs `80 on each chain; the

eccentric 92, rod 94, pawl 96 and ratchet wheel 97 (Fig. 1) fun tioning predeterminedly to this end. A as these chains carry the lugs 80 they convey the opened blank forward `and toward the discharge end`f200 (Fig. 1 of the machine; the effect of this operation being that every division of the chains 76 and 77 contains one opened blank and maintains said blank open at least until it has been transported beyond the outer limits of tracks 32, 33, 34 and 35.
